This multipart animation series explores the process of photosynthesis and the structures that carry it out.

This animation shows how mutations in an ion channel protein lead to the genetic disease cystic fibrosis. The animation also discusses how research on this protein has been used to develop treatments for the disease.

This animation shows how the cancer treatment Gleevec inhibits the cancer-causing protein BCR-ABL.

This animation shows why a mutant BCR-ABL protein is resistant to the cancer treatment drug Gleevec, and how a new drug can overcome this resistance.

This animation zooms into a 3D model of dengue virus, moving from the virus’s outer structures to its inner core.

This animation shows how dietary fat gets digested, packaged, and sent to various tissues for storage or energy.

This animation shows how DNA molecules are packed up into chromosomes.

This animation shows the translation of messenger RNA into protein.

This animation shows the translation of messenger RNA into protein and details the interactions between the transfer RNA molecules and the ribosome.

This animation describes how many nucleotides encode a single amino acid, which is a key part of the genetic code.

This animation shows how proteins in the cell are tagged for disposal by ubiquitin and then degraded by the proteasome.

This animation shows how the p53 protein binds to DNA to initiate transcription.
